Java 异常java.lang.IllegalArgumentException: Illegal group reference

当字符串方法replaceAll()中替换字符含有特殊字符$如，

String test  = "<StreamingNo>abc</StreamingNo>";
test = test.replaceAll("abc", "1111111111$$");

会报异常，解决方法为改写以下形式：

test = test.replaceAll("abc", java.util.regex.Matcher.quoteReplacement("dXNlcjM1NDk2NQ$$"));
